Minn Kota Prop Cage

Elkana contacted me with the idea of designing a trolling motor cage. I actually do not have the motor so the measurements might varies... This is my first attempt to have this cage for a motor.
I used the following measurement, after confirming with Elkana:

mount_ring_outer_dia=83.44mm
cage_ring_outer_dia=280mm

The cage ring and the mount ring is 50 mm apart

The mount ring and the cage ring is printed in two pieces each and 3mm stainless bolt and nuts shall be used to put them togeth
